What is Asphalt Prime Coat?

The shear strength of the final asphalt product is affected by the quality of the asphalt prime coat applied.  Asphalt Prime Coat is also termed as emulsified asphalt, water diluted asphalt and Cutback aliphatic spray. Recently I have got the chance of working on a highway project somewhere in a mountainous cold-weather region. And I was amazed after finding the impact of climate on…

What is Soil Cement

We know that soil clay or sand is capable of withstanding heavy loads but is subjected to settlement, consolidation and deformation, which if not controlled, result in shear failure or an ultimate collapse of the structure. Actually it is a known fact that while mixing different construction material would also combine their positives. So Soil Cement is one of that positive combining the…
