Abstract of the Disclosure Asphalt roads or the like are repaved by heating and decomposing existing pavement with microwave energy and then remixing and recompacting the constituents of the pave- ment, the operations being performed at the original location of the old pavement and in some cases without removing the pavement constituents from the roadbed itself. A microwave energy applicator may be traveled along the pavement in front of remixing, grading and compacting equipment or some or all of the equipment may be integrated into a self-propelled vehi- cle. The vehicle may carry a microwave applicator followed remixed means such as rotary tillers or the like and grading and compaction devices, and may travel continuously down a road which is reconditioned as the vehicle progresses. Motor generator sets on the vehicle power the microwave sources and the hot exhaust from the motors may be directed to the pavement to supplement the microwave heating and to maintain high temperatures during the additional operations. Appa- ratus is provided for efficiently coupling microwave energy into underlying pavement and for inhibiting the escape of useful for heat treating concrete or the like as well as asphaltic pavement.
