Asphaltic plug joints for bridge (thorma joints)

ATAYA is an ENNIS FLINT-approved Applicator for the delivery and installation of the Thormajoint bridge joint range according to the Specification of Asphaltic plug joint.

ThormaJoint is a combination of an elastomer-modified bitumen binder known as BJ200 and a carefully selected single-size aggregate.  The joint is constructed in layers, in-situ, and is a hot process.

BJ200  is manufactured by  ENNIS FLINT  and is a  special blend of bitumen, polymers, fillers, and a surface-active agent formulated to combine good fluidity at process temperatures with low-temperature flexibility and ambient temperature flow resistance.  It is delivered to site in bags in its solid-state, where it is heated in special boilers (double oil jacketed boiler)  to its normal application temperature.

Why Thorma Joint?

• Very low and easy maintenance.

• Low surface noise & excellent ride quality.

• Excellent Durability.

• Able to withstand extremes of temperature.

• Flexible and waterproof.

• Ability to accommodate longitudinal, rotational, and transverse movements.

• Quick installation, thereby minimizing disruption to traffic flow.

• Can be used across the full depth of the bridge.

Elastomeric Bridge Bearings For Constructions-ATAYA EGYPT

Elastomeric Bridge Bearings-Quality Construction Products In Egypt

Like all reinforced concrete metallic structures, bridges are also subject to certain movements. They are caused by temperature variations, wind load, traffic movements, or seismic activities. Modern bridges, unlike conventional bridges, have longer spans and are lighter in construction and hence have high chances for a wider range of movements.

If the relative movement between the bridge superstructure and substructure is restricted, a large number of forces may develop in the girder or the substructure. It can push its supports thereby causing damage to the bridge. Elastomeric bearings are hence used to allow necessary relative movement between the girders and the substructure. They are placed on the bottom of the substructure, i.e., below the girder and above the pier cap, over a pedestal. It is an interface between the superstructure and the substructure.

Generally, elastomeric bearings work in three broad areas as below:

They allow the ‘permitted’ longitudinal and rotational movements.

Prevent those ‘not permitted’ undesirable movements.

Transfer load from the superstructure to the substructure.

Interestingly elastomeric bearings have no moveable parts and hence the movements are absorbed by the bearings in the form of shear. There is no sliding motion that occurs between the pad and the beam or between the pad and abutment unless some sliding elements are already designed into the surface of the bearing.

Role of an Elastomer

Engineers understand elastomers less than they do concrete or steel because the elastomers do not obey Hooke’s Law. They are very flexible in shear but very stiff in bulk compression. The simple theory of mechanics characterizing the behavior of rubber is quite different from that used for conventional materials. Some of those striking features of elastomers are as follows:

Since elastomers do not follow Hooke’s Law, the modulus of elasticity-E is not constant.

The shear modulus-G is fairly constant and hence it becomes more relevant during elastomeric bearings design.

The coefficient of friction between the elastomer and the base material is fairly unaffected by the nature of the contact surfaces whether it is steel or concrete.

The coefficient of friction between the elastomer and the base material reduces with an increase in normal load on the bearing

Except under extremely low temperatures, the performance of the elastomeric bearing is unaffected by temperature variation.

Under the effect of cyclic loading elastomeric bearings become more flexible.
