The Throop Company has worked as a sub-contractor for Caltrans for many years. We have worked on freeways, highways, on-ramps and roads all over California. Below are photos of an on-ramp repair project. After placing Rapid Set® concrete Caltrans was able to open back up to traffic in less than 2 hours. Extensive testing is part of every Caltrans project.
