What is CBR value?
The California Bearing Ratio (CBR) is a measure of the strength of the subgrade of a road or other paved area, and of the materials used in its construction. The ratio is measured using a standardized penetration test first developed by the California Division of Highways for highway engineering.

What is a right of way in British Columbia?
A right-of-way is a strip of land on which a FSR exists or will be constructed to provide access for approved logging operations. Clean energy projects, including independent power producer (IPP) projects, may be proposed within or adjacent to an existing forest road right-of-way.
Which is the best bitumen mix for highway construction?
The bituminous concrete grade-2 of NMAS 9.5mm has been efficiently used in the highway construction for the US. For higher traffic BC grade-2 are recommended. The semi-dense bituminous concrete mixes have neither dense or open graded characteristics. It consists of the so called pessimum voids when they are fully constructed.
