Float Test Apparatus
 Used to determine the floating time of bituminous materials.
 Consists of an aluminum oat and a brass collar filled with bitumen to be tested. 
 The specimen in the mould is cooled to a temperature of 5°C and screwed in to oat. The total test assembly is floated in the water bath at 50°C and the time required for water to pass its way through the specimen plug is noted in seconds and is expressed as the oat value.
 ASTM D139  AASHTO T50

Skid Resistance Tester
 Used to measure antiskid performance of high grade roads.
 Thermometer range –10 to +110 °C for surface temperature measurement.
 Stool, wash bottle, bristle and tool set for machine use.
 Carrying case.
 The base has three adjustable feet so that the swing of the pendulum during the test moves through a truly circular path while operated directly on a road surface.
 Additional incorporated scale for tests on Polished Stone Value specimens.
 Rule, made of plexiglass, for sliding length verification

Specific Gravity and Water absorption
Density Basket, A wire basket of not more than 6-3 mm mesh or a perforated container of convenient size 20 cm dia x 20 cm high with wire hangers not thicker than one millimetre for suspending it from the balance. 
 Balance -A balance or scale of capacity not less than 3 kg
 Suitable for operation on 220 V, 50 Hz, Single phase, AC supply.
 A container for filling water and suspending the basket.
 A shallow tray and two absorbent clothes, each not less than 75x45cm.
 1. A thermostatically controlled oven to maintain temperature at 100-110° C.
