Rigid pavements comprise 6 percent of paved roads (about 2 percent of Hawai'i roads). Figure 1: Rigid and flexible pavement load distribution. Each of these pavement types distributes load over the subgrade in a different fashion. Rigid pavement, because of PCC's high stiffness, tends to distribute the load over a relatively wide area of ...

airport airport Runway pavements: Until the introduction of heavy monoplane aircraft in the latter part of the 1930s, civil airtransport aircraft were able to operate from grass runways with takeoff distances of less than 600 metres (2,000 feet). The advent of heavy aircraft such as the DC3 required the provision of paved runways; at the same time, takeoff distances increased to more ...

Joint Spalling in Rigid Pavements Excessive compressive stress causes deterioration in the joints, called as the spalling. This may be related to joint infiltration or the growth of pavement, that are caused by the reactive aggregates. Poor quality concrete or construction technique will also result in joint spalling. Small edges to large spalls in the back of the slab and down to the .
