Infrastructural Projects
Major infrastructural projects have been done in India and the rest of the world. It has been observed that poor infrastructure have contributed to economic down turn and loss in business. In the recent years this issue has been addressed through a major construction drive of roads.

Asphalt Vs. Concrete Roads
There has also been a continuous debate as to the quality of asphalt versus concrete roads. Many expatriates have been able to prove that concrete roads last longer, are cheaper to construct and have lower maintenance costs compared to asphalt roads.

A quick survey at the concrete road networks in the world reveals that most of the highway networks in the United States alone are concrete roads.  In India, the Mumbai – Pune expressway is an Iconic concrete road project, and the current government is supporting major road construction projects done with concrete.

Quality Concrete Roads
Unlike asphalt roads, concrete roads are never easy to repair and once done, repair is very costly. The only sure ways of guaranteeing quality has been the use of the slip form paving technology. This has in turn led to a gradual increasing demand for the slipform paver, and this trend is set to continue.

From the trends observed, the machines able to give greater output have been more preferred over the old model paving systems. Despite there being other supporting projects, like water canals, the main driver of demand still remains roads and kerbs construction.

Successes of the Slipform Pavers in Africa

With majority of the developing countries being in Africa, this region has become an emerging market for slip form pavers India manufacturers. In the North African countries such as Algeria, the slip form paver has been successfully used to build a 1216 km, three lane highways that ultimately link Morocco, Algeria, Tunisia and Libya. With this innovative technology the project was completed in just three and a half years.

In the nation of Nigeria and the state of Kogi, a new 24 km road was done using the slip form paver technology. This development set a precedent for road construction in the country. This fact is also supported by the fact that areas receiving high rainfall are better served by concrete roads as compared to the bitumen roads which would wear and tear faster.

East African Region

In the east African region, developing countries such as Kenya, Uganda and Tanzania have created a heavy demand for the paving equipment, occasioned by the budgets to construct thousands of kilometers of road.

Important Innovations in Paving Equipment

Fuel efficiency is one area of Innovation that HEM slip form pavers manufacturer has succeeded. That has served to enhance the product demand since fuel is a major cost in concrete paving.

Slip Form Paver – Unique Technology Machines

The slipform paving is a concrete molding process where concrete is dispensed into a continuously moving mold to attain the required shape or design. This technology is applied in heavy constructions such as roads, bridges and heavy buildings. The main advantage of this technology is the creation of a continuous, “cast in Place” and almost flawless structure that has superior performance over other methods such as molds and discrete blocks.

Other Benefits of Slipform Paving

Types of slip form pavers Available

Various types of slip form pavers are available in the market depending on the output specifications of each model. Manufacturers of these equipments also classify their machines based on the individual features unique to the equipment. Some of the different functions of these equipments may include;

Technology Involved In Manufacturing Slip Form Pavers

The slip form paving technology is based on the rapid setting properties of concrete material. The technology works on a balance between the quick settings of the concrete and remains workable enough to be molded into the form. This balance is crucial to ensure the final structure is strong and durable.

How the Slip Form Paver Works

The concrete used in this system of paving is very similar to that used in convectional paving systems. It must have a good and uniform consistency having a slump of approximately two inches. This concrete is deposited into the hopper box from where the machine evenly distributes the material across the paving surface. The paver machine helps in achievement of a homogenousmix and compaction through a system of hydraulic or electric vibrators, while the mold helps in forming the slab to the desired thickness and width.

Demandof Slip Form Pavers

The global demand for slip form paving technology continues to increase as more and more pavement roads are required. The market for concrete paving machines is seen to be growing at a rate of 15-20% every year and industry analysts fore see a more rapid growth by the end of year 2017.This is boosted by increasing road networks in various countries ,time bound projects requiring very high efficiency and expansion projects of airports,and residential areas. In India, the government’s plan to construct over 20 kilometers per day of road has created a sufficient demand-pull for these equipments. Some of the global leaders in slipform paver manufacturing includes Apollo Inffratech.

The slip form paving technology is one of the advanced forms of technology that is used for the purpose of paving construction works. The construction materials (PCC) are continuously prepared and poured over the paving surface and the leveling is done simultaneously. The pulling is done constantly to help in the consolidation process. The Slipform Pavers are the machines that are used for this type of topping. There are several advantages achieved by availing this form of paving. Take a look at the major benefits of selecting this type of surfacing.

Best Precision is available: When this machinery is used, the precision levels of the surfacing are very high. The conventional forms of topping cannot be error-free. There may be defects such as undulations. The defects can be minimized the most if this form of surfacing technology is adopted. The Slipform Pavers are used for the surfacing of the best quality roads.

Low Slump PCC is used: This type of technology always makes use of low slump PCC. This means that the water content in the PCC mixture is the minimum. The concrete settles down faster than the traditional form of surfacing. The strength of these paving is found to be more. The roads which need to be built very fast always use this technology.

Reduction in Labor Costs: The entire operations are mechanized. The use of manual labor is nearly done away with. This eliminates the high labor costs that are involved in the traditional form of paving. The job is entirely carried out by the machines. Only a single machine can carry out the jobs of many labors at a time. Chances of chaos due to excessive labor are also curtailed.

Best for Large area of Paving: Many a time, a large stretch of area needs to be paved or metaled. These machines are the most suitable to use during this period. The conventional method of topping would take longer for the job. There is also an uniformity in the paving process. This is possible only because the entire operation is mechanized. Manual jobs are not involved.

It is a Faster Process: The entire process can be done faster than the traditional surfacing. When roads and pavements are to be constructed, this technology helps in opening up these places for public use at the earliest. You cannot afford to keep these places unusable for long. Otherwise, a huge amount of inconvenience is caused to the common people. The consolidation of the laid materials also takes place faster. If a double layering needs to be done, this is the best option that should be exercised.

It Creates Better Looks: If you want the topping to look good free from defects, this is the method that you must adopt. No other type of surfacing can give a neater appearance. The major roads should always be paved in this manner.

These are the main advantages of implementing this type of surfacing. It may be expensive but is always the best form of paving.
