    https://www.calvacpaving.com/ Calvac Paving was proud to be able to serve the city of Los Altos, California by replacing a common private road within the community. The roadway needed repair for durability, safety and aesthetic reasons, giving Calvac Paving the opportunity to once again demonstrate the quality and attention to detail of our work.

    This project required some delicate handling because, as a private road in a residential area, Calvac Paving had to be mindful of residents’ access needs as well as the possibility of fires or other emergencies. It also necessitated using a special process that allowed for minimum road closure time and maximum performance. We created a short video to show the highlights of the paving process, from top to bottom.

    The process Calvac Paving decided to use was a “petromat” overlay on top of the existing roadway. To do this, the failed areas were prepatched using full depth hot mix asphalt. Once this was done, the existing utility boxes in the roadway were raised up, so as to secure them against further failures in the subgrade or roadway itself. An asphalt binder and paving fabric were installed next, allowing the existing road surface to bond properly to the hotmix upon placement. A 2” lift of hotmix was placed using a self-propelled paver, and then the lift was compacted to produce a smooth, level road surface. Show less
