The paving roads, streets and runways of airport  with asphalt require to testing their validity after completion paving. One of these testing it’s the tropical roads test device, but must solving it by simplest technique and lower costs and that which make it in our invention. We had made design and manufacture experimentally the device to  testing tropical roads, streets and runways of airport after paving with asphalt, so the device is the mechanism car which can controlled it by remote control or mobile device which testing the bumps to the data location sent from computer associated memory slice in it. We had designed and execution the device experimentally at the paving area road then proved its efficiency.
