The invention provides a high-strength composite pavement and construction technology thereof mainly to improve road safety and solve the problem of frequent road maintenance. The high-strength composite pavement has the advantages of not only meeting the requirements of cushion function and strength on one hand, but also avoiding the use of sand and concrete, saving construction cost and shortening construction period on the other hand with the mixed rolling of split soil curing agent and plain soil to form cushion, and not only greatly improving the bearing capacity of foundations, preventing uneven settlement of soft foundation roads and effectively restraining the lateral displacement of the soil on one hand, but also reinforcing foundation paving materials, increasing service life andreducing maintenance on the other hand with plastic-steel geogrid sandwiched in a subbase. The construction technology of the high-strength composite pavement has the advantages of being simple, suitable for ordinary soft foundation road construction, short in required actual construction period, strong in the bearing capacity of completed constructed pavement , and high in overall economic benefit.
