#KLANG GROUP ENGINEERING & CONSTRUCTION

Every road leads to a different destination The construction of a new road – whether from asphalt or concrete – requires the production of an excellently bonded pavement structure, beginning with a stable base layer and going all the way to a precisely levelled surface course. What are the most important criteria to be considered? What methods need to be applied? What machines used? The base course serves as a foundation for the paving. Depending on the stresses to be expected, the road comprises various layers of different thickness in order to withstand the most diverse weather conditions and remain serviceable for many decades. The bottom layer essentially comprises an unbound mixture of coarse and fine crushed stone, as well as crushed sand, to achieve the desired load-bearing capacity and absorb traffic loads so that the underlying subgrade is not deformed Paving a hydraulically bound base layer. Precisely metered quantities of cement slurry are added via hose conne

A pothole is a form of asphalt failure caused by a combination of water and traffic pressure. Potholes are a reality of life in MALAYSIA and across the globe. While it is nearly impossible to entirely prevent potholes from forming, understanding their causes can help you minimize their effects. What Is Asphalt? To truly understand what causes potholes, it is important to first understand what makes up asphalt. An extremely common and sustainable paving material, asphalt consists of aggregates, binders, and fillers. The aggregates vary, but are generally composed of gravel, sand, or rocks ground to different consistencies. Binders such as bitumen give asphalt a remarkable adhesive quality, holding it together and making it easy to pour and spread. Asphalt is normally heated before pouring to give it a longer workable time and to allow it to cure as it slowly cools. What Is a Pothole? A pothole is an unevenly cracked area where the asphalt is washed out or worn away. Potholes

How Do Potholes Form? As vehicles pass across asphalt, the friction from the tires causes it to expand. Over time, this can lead to surface cracks in the asphalt. When it rains or snows, water seeps into those cracks. That water can gradually erode the asphalt from underneath, causing larger cracks and divots to form. Our malaysian wheather add to the problem, because water can actually freeze inside the cracks. The expansion of water into ice pushes out the asphalt, often somewhat violently. When the water melts and contracts, there is nothing left in the space that the ice once occupied. This speeds up the erosion cycle, often causing large divots to appear quickly. Whether the divot was left by freezing and thawing, or simply eroded over time, the end result is the same—a gap underneath the surface pavement. Then, when a vehicle drives over the divot, the weight pushes down on the divot, allowing it to collapse into a hole. As more vehicles drive over the pothole, the cra

It’s never too late to learn something new, and when it comes to  asphalt pavement installation , there are many things that homeowners, commercial property owners and municipality employees many not be aware of.  At Wolf Paving, we are asphalt paving contractors in Milwaukee, Oconomowoc and Madison who take pride in educating people about everything asphalt — it’s our passion.  So please, take a look at this step-by-step overview of what an asphalt pavement installation requires — from demolition all the way to a smooth, new surface.  Step 1: Demolition and Removal The first step in the asphalt installation process is to remove the existing surface, whether it is asphalt, concrete or pavers.  Demolition and removal is completed using heavy machinery, including small bobcats and forklifts and when necessary, front loaders and large dump trucks. Debris is removed and in most instances, Wolf Paving recycles the old asphalt and concrete in our  asphalt plants , turning det

We specialize in infrastructure and road paving assessment and in building preventative maintenance programs that help you extend the life span of your roads and highways. Many of our roads and highways are nearing the end of their life span in an environment of population growth, increased density, and increased movement of people, goods and resources across Malaysia. Decisions to build or rehabilitate roads must be made with the goal of achieving the highest value for the expenditures. In this environment, it is of significant importance to ensure that infrastructure spending is a longer term investment.
