Influence of Foundation Strength on Concrete Pavement Thickness . The curing compound also serves as a bond breaker between the subbase and the concrete 

Lean concrete has been widely used as the typical subbase for jointed concrete pavement in Korea. Generally, polythene sheet is placed between the lean concrete subbase and the concrete pavement slab as a friction reducer. In addition, an asphalt bond breaker may be used as an alternative friction reducer in some cases.

Street creep is a problem that is caused by thermal expansion and contraction of exterior concrete pavement that surrounds a home. As this concrete expands against a driveway with inadequate expansion joints, the driveway is pushed against the garage slab, which in turn pushes against the foundation, causing damage.

4. Lean Concrete Base for Pavement Construction. The construction of the base by lean concrete is performed in a similar manner to that of conventional concrete. The equipment used for conventional base construction can be used for a lean concrete base by the contractor. This helps to distribute the mobilization cost to a greater scope of the work.

6.3.2.5. Extend geotextile beyond both edges of the new concrete pavement at least 6 inches. Geotextile is designed to flow water laterally through the geotextile. The six-inch tail on the outside of the pavement allows for overlap bonding and may be connected to a drainage system to flow water away from the pavement. 6.3.2.6.

Resonant pavement breaker is an excellent technique to reform worn cement concrete pavement (PCC). When the frequency of the machine adjusted to the resonant frequency of the worn cement concrete pavement, the pavement will be broken to discrete blocks. For the full use of this technique, this article studied the dynamic properties such as natural frequencies and modalities of worn cement
