A waterproof expansion joint comprises a ballast protection plate and at least one locating device configured to retain the ballast protection plate over a deck joint. A flexible sealing member located below the ballast protection plate can include at least one flange portion and at least one expansion feature. Each expansion feature can include a shape preformed into the flexible sealing member extending downward into the deck joint and configured to deflect, enabling variation in the width of the flexible sealing member to match the width of the deck joint.

A transformed continuously reinforced concrete pavement structure using a short reinforcing bar and crack induction. The structure includes a crack induction part combined with short reinforcing bars spaced apart from each other. The short reinforcing bars replace continuous reinforcing bars in a concrete pavement layer of a continuously reinforced concrete pavement structure.

A pavement slab includes a top surface, a bottom surface opposite the top surface, first and second longitudinal side surfaces, each of which extends from the top surface to the bottom surface, and first and second transverse side surfaces, each of which extends from the top surface to the bottom surface. At least one transverse tube is positioned intermediate the top surface and the bottom surface and extends from an inlet at the first longitudinal side surface to a second end intermediate the first and second longitudinal side surfaces. The at least one transverse tube is sized and shaped to convey a binder material. At least one vertical tube extends from each of the at least one transverse tube to the bottom surface. The at least one vertical tube is sized and shaped to convey the binder material.

A system which creates a durable seal between adjacent horizontal panels, including those that may be curved or subject to temperature expansion and contraction or mechanical shear. The durable seal system incorporates a plurality of ribs, a flexible member between the cover plate and the ribs and may incorporate a load transfer plate to provide support to the rib from below, and/or cores of differing compressibilities.

An expansion joint seal includes a seal body and a plurality of seal caps, wherein the seal body is made of a material having a first hardness, and the seal caps are made of a material having a second hardness that is greater than the first hardness. The seal body includes a plurality of walls that form hollow cells. The seal body includes a plurality of traffic bearing surfaces that are separated from one another by grooves and are thereby discontinuous relative to one another. The hollow cells and the grooves allow the seal body to expand and contract as an expansion joint increases and decreases in size due to thermal and/or load variations. The seal caps cover the traffic bearing surfaces of the seal body, such that each of the traffic bearing surfaces of the seal body is covered by a separate one of the seal caps.

The present invention relates to a method for installing a crack inducing expansion joint filler when placing concrete so as to reduce cracks generated during concrete construction, and an apparatus therefor and, more particularly, to a method for installing a concrete crack inducing expansion joint filler and an apparatus therefor which can vertically install and fix a plurality of fixed rod shafts on a bottom surface, place concrete, and then fit connection means to the fixed rod shafts while connecting and installing a joint filler member, having a cover means which can be attached and detached between the connection means, before the concrete is cured. Thus, since it is possible to install the joint filler member at the same time as placing the concrete on the bottom surface the method and apparatus can significantly reduce the concrete construction period and also cause that cracks generated by the joint filler during concrete curing can be reduced to a minimum, thereby increasing concrete durability and enhancing construction efficiency.

A concrete expansion joint insert includes a body having two ends, two longitudinal edges between the ends and two side surfaces between the longitudinal edges. The body has a length, a width and a thickness. The length is greater than the width and the width is greater than the thickness. The width and thickness correspond to dimensions of the ends of the body. The length and the thickness correspond to dimensions of the longitudinal edges. The length and the width correspond to dimensions of the side surfaces. At least a portion of the body has a first surface characteristic and at least one of the longitudinal edges has a second surface characteristic that is different than the first surface characterization. The second surface characteristic comprises at least one of a color, a texture and a profile.
