Construction and Rehabilitation of Aircraft Pavements Using Concrete Blocks Having Mechanical Interlock
ثبت نشده
چکیده
The first use of concrete block paving for improving existing aircraft pavements was made at London Luton Airport UK in October 1981. Initial trials comprised two rectangular panels each 9 m x 2 m constructed on an apron stand directly beneath undercarriage gear positions. Rectangular block paving units 100 mm x 200 mm x 80 mm thick were used as an inlay to replace damaged bituminous overlay material. Block paving surfacing has now been adopted worldwide with some 1.5 million m 2 now in use.

Determining the Relative Importance of Parameters Affecting Concrete Pavement Thickness
Spending costs in construction of road pavements has turned this subject into one of the significant points in transportation infrastructure of countries. Concrete slabs consider as a paving method with ability of reducing the rehabilitation needs. Therefore, to manage costs and optimize the thickness of concrete pavements, recognizing the amount of determinative factors’ influence will be requ...
متن کاملEvaluation of Rough Set Theory for Decision Making of rehabilitation Method for Concrete Pavement
In recent years a great number of advanced theoretical - empirical methods has been developed for design & modeling concrete pavements distress. But there is no reliable theoretical method to be use in evaluation of conerete pavements distresses and making a decision about repairing them. Only empirical methods is used for this reason. One of the most usual methods in evaluating concrete paveme...
متن کاملPerformance of Dowel Bar Retrofitted Concrete Pavement Under HVS Loading
The California Department of Transportation uses Dowel Bar Retrofit (DBR) as a rehabilitation strategy for concrete pavements. Two test sections were dowel bar retrofitted and a third section was designated for control on US 101 near Ukiah, California. All three sections were subjected to accelerated pavement testing using the Heavy Vehicle Simulator (HVS). The HVS results demonstrated a large ...
متن کاملDesign of green engineered cementitious composites for pavement overlay applications
The construction, repair and rehabilitation of concrete pavements relies on the production and flow of large quantities of concrete and its constituents. Within the US, nearly 43 megatons of cement are used annually for the construction, repair and rehabilitation of concrete pavements, accounting for over 39 megatons of CO2 emissions. To reduce environmental impact and improve the sustainabilit...
