PHF

Give Way Intersection 

PROJECT- 2018


This rest area is situated just off a very busy highway and experiences extreme amounts of through traffic on a daily basis.  The Give Way area is prone to unravelling and potholing which causes road users to experience a negative experience when leaving this complex.  Gravel Lock put down a trial of PHF Coldmix Pothole Fill, in the middle of winter, next to traditional fill for the owner to assess the viability and longevity of the product. The PHF is still strong and well bound after 2 years!
