4. PLACING OF MORTAR
THE MORTAR SHOULD BE PLACED IN LAYERS OF ABOUT 20mm THICK. COMPACT EACH LAYER THOROUGHLY OVER THE ENTIRE
SURFACE USING A WOODEN TROWEL OR HAMMER. GENERALLY, THERE SHOULD BE BO TIME DELAYS BETWEEN THE PLACING AND
COMPACTING OF LAYERS.

5. CURING
ALL TYPES OF CEMENT REPAIRS NEED THOROUGH AND CONTINUOUS CURING TO DEVELOP THE DESIRABLE STRENGTH AND
IMPERMEABILITY, AND TO MINIMIZE DRYING SHRINKAGE WHILE BOND STRENGTH IS DEVELOPING.

DESCRIPTION OF REPAIR METHOD S-12 SCALE 1:5 Mts.

THE QUALITY AND MAINTENANCE OF THE EXPANSION JOINTS ARE VITAL TO

THE BEHAVIOR OF THE BRIDGES AND ITS DURABILITY. ACCORDINGLY, IT SHOULD
BE ENSURED THAT EXPANSION JOINTS ARE WATERPROOFED AS WELL AS
RESISTANT TO LEAKAGE. IN THE CASE OF SEALANT ASPHALT, THE SEALANT IS SEE ASPHALTIC PLUG JOINT DETAILS
EASILY DAMAGED DUE TO TRAFFIC LOAD AND AGING.
THE USUAL GAP BETWEEN CONCRETE EDGES IS AROUND 20mm
CONSIDERING TEMPERATURE IN THE PHILIPPINES AS 27°C±10°C. THE
MOVEMENT OF A 20m BRIDGE SPAN DUE TO CHANGE IN
TEMPERATURE IS 12x10-6/°C x 20m x (±10°C) = ±2.4mm AND THE
MOVEMENT OF THE SAME SPAN DUE TO TRAFFIC LOAD IS
APPROXIMATELY LESS THAN 5mm. TOTAL MOVEMENT OF A 20m
SPAN RCDG BRIDGE IS BELOW ±10mm. WITH THESE
CONSIDERATIONS, THE MOST SUITABLE REPAIR MEASURE FOR
DAMAGED ASPHALT SEALANT IS THE INSTALLATION OF ASPHALTIC
