The present invention discloses a method for relieving vaulted expansion of a cement-stabilized base layer through precut seams. The method firstly establishes an RBFN model according to a large number of observation results of a vaulted expansion amount of the cement-stabilized base layer under different conditions (such as temperature and a stress release structure) in Xinjiang and similar regions; and on such a basis, the vaulted expansion amount of the cement-stabilized base layer to be designed is predicted. When the vaulted expansion amount is greater than a control requirement, the RBFN model is configured to design a reasonable width and a reasonable interval of the precut wide expansion seams to ensure that the vaulted expansion amount of the cement-stabilized base layer is less than a control value. Based on the design of the RBFN model, the present invention provides a corresponding construction method for the precut wide expansion seams. The present invention can predict the vaulted expansion of the cement-stabilized base layer without precut seams according to existing data.

A method for the preparation of concretes with improved wear resistance. The method involves the use of colloidal silica, which is added to a concrete mixture after mixing, in conjunction with a concrete cutter, which is added to the concrete mixture after the addition of the colloidal silica.

A system for re-surfacing a pavement surface includes a mobile vehicle having a first longitudinal axis and a material delivery mechanism having a second longitudinal axis. The system also includes an actuation system coupled to the mobile vehicle and to the material delivery mechanism. The actuation system is configured to actuate the material delivery mechanism with respect to the mobile vehicle such that the first longitudinal axis is oriented obliquely with respect to the second longitudinal axis.

A paving mixture for application to a surface and a method for the same. The mixture comprises a binding material layer applied to the surface to form a base layer on the surface, and an aggregate material layer applied on top of the binding material layer, wherein the binding material layer comprises at least 15% of the bitumen in the paving mixture by weight, the aggregate material layer contains an asphalt mixture that provides a road surface, and the aggregate material layer and the binding material layer are combined on the surface within 30 seconds of application of the binding material layer.

A rut testing apparatus for testing the susceptibility of a pavement specimen to rutting has a specimen holder for supporting the specimen to be tested, a wheel, and a sensor. The specimen holder is arranged to support the specimen from below and to support two opposite ends of the specimen. The specimen holder is arranged to allow the specimen to deform in a lateral direction LD that is transverse to a direction that extends between the opposite ends. The wheel is arranged to move along at least part of the specimen in the direction that extends between the opposite ends. The sensor determines deformation of the specimen in the lateral direction LD.
