Abstract
Membranes are provided which minimize reflective cracking in the repair of roads. The membrane comprises a reinforcement along with a binder having a high modulus of elasticity and a binder having a low modulus of elasticity. The high modulus binder impregnates the reinforcement and is adhered to the distressed road whereas the low modulus of elasticity material is adhered to the impregnated reinforcement and is used in contact with the subsequently applied asphaltic overlay.
