When spreading aggregate material onto a layer of bitumen/wet bitumen, when forming a road surface, the aggregate is commonly spread from a truck in reverse, potentially causing accidents and injuries. Safety is improved by providing a spreading vehicle that can be driven in the direction in which it is spreading the aggregate material. This is achieved by providing a second driving cab and driver controls at a location that would normally be considered the rearward end of the vehicle. The second driver cab is above a conveyor system conveying aggregate material from a hopper of the vehicle to a spreader box. The second driver cab allows the vehicle to be driven in the direction it is spreading material, by a driver who is facing the direction of travel, and who can see if the vehicle is about to hit anything or run into a worker in the surrounding area.
A steerable road construction materials spreading vehicle, the spreading vehicle having a front end and a rearward end, and having a container configured to hold road construction materials, a spreader box situated at or adjacent the rearward end of the spreading vehicle and configured to apply the road construction materials along a road way;
The steerable road construction materials spreading vehicle as claimed in 3, wherein the rearward driving module also includes controls for the spreader box.
A steerable road construction materials spreading vehicle capable of spreading aggregate stone when travelling in reverse, the spreading vehicle having a front end and a rearward end supported by at least front wheels and rear wheels, a first set of driving controls situated at or adjacent the front end of the vehicle allowing the vehicle to be driven/steered from the front of the vehicle and having a container suitable for containing aggregate stone for spreading onto a road way, a spreader box situated at or adjacent the rearward end of the spreading vehicle and spaced apart from the rear wheels and extending substantially across the width of the spreading vehicle and configured to apply the aggregate stone in advance of the vehicle's wheels when the vehicle is reversing so that the aggregate stone can be applied on top of freshly laid bitumen on a road way;
A method of forming a bitumen sealed road surface at a road construction site using a road construction materials spreading vehicle having a front driving module at the front of the vehicle and a rear driving module at the rear of the vehicle, the method including the steps of:
