MAINTENANCE OF BITUMINOUS SURFACING
The type of defects in bituminous surfacing are grouped under four categories:
a) Surface defects which include fatty surfaces, smooth surfaces, streaking and hungry/dry surfaces.      
b) Cracks which cover hairline cracks, alligator cracks, longitudinal cracks, edge cracks, shrinkage cracks and reflection cracks.      
c) Deformation defects, which comprise of slippage, rutting, corrugation, shoving, shallow depressions and settlements.      
d) A disintegration defect, which consists of stripping, loss of aggregates, reveling, pot-holes and edge breaking.      
The general causes and remedies for these defects are given as below :
a) Surface Defects
Natural Defect Cause Remedy  
Fatty surfaces
 
Excess bitumen, soft grade of bitumen, non-uniform spraying and loss of cover aggregates as in surface dressing, heavy axle loads. Apply hot dry cover aggregates or sand and roll gently for removal of excess binder; burn it, if necessary or relay area affected.
Smooth surfaces Polishing of aggregates by traffic, excess binder. Resurface with premix carpet using hard aggregates or with slurry seal
rich lines of bitumen in surface dressing) in longitudinal/ transverse direction. Hungry / Dry surfaces.

 
Non-uniform application of binder, low temperature of binder, manual spraying, mechanical faults during spraying. Use of insufficient binder, use of absorptive aggregates, loss of aggregates from surface. Apply new surface dressing with proper care in spraying of bitumen. Apply slurry seal, or for emergency repair apply fog seal.
b) Cracks
Hair-line cracks (fine cracks at close intervals).
 
Insufficient bitumen, excess filler, compacting when too hot, over compaction. Apply fog-seal with bitumen, cutback bitumen or bitumen emulsion.  
Alligator cracks (interconnected cracks forming a series of blocks) Excessive movement of base or sub-base layer, base saturation, excessive leads over weathered surfacing, inadequate pavement thickness. Fill crack with bitumen emulsion or cutback bitumen and apply slurry seal or sand-bitumen mix, install drainage.  
Longitudinal cracks (at the joint between pavement and shoulder or at the joint between two paving lanes). Contraction or movement of sub-grade beneath shoulder, lane joint crack due to weak joint or differential frost heave along centre-line. Fill and seal cracks with cutback bitumen or bitumen emulsion, apply sand-bitumen mix, if cracks are wider than 3mm.  
Edge cracks (parallel to outer edge of pavement 0.3 to 0.5m. inside) Lack of lateral support from shoulder, poor surface drainage, base saturation shrinkage, frost heave inadequate pavement width. Rectify drainage system, provide hard and paved shoulders, fill cracks and lay premix carpet with seal -coat, if edge of the pavement has settled, bring it upto the desired grade with plant mix patching material.  
Reflection cracks (usually in over lays over cement concrete or badly cracked bituminous base). Due to joints and cracks in the pavement layer underneath. Fill cracks and seal suitably depending on size of crack. Apply a crack relief layer for prevention of such cracks.  
c) Deformation defects
Rutting (Longitudinal depressions or grooves in wheel tracks). Heavy channelized traffic, low stability of mix due to inadequate compaction, weak pavement, high intensity of load stress as from bullock carts, plastic deformation. Fill ruts with premix carpet and compact. Relay affected portion with bituminous mix of good stability if necessary.  
Corrugations (Regular undulations causing shallow wavy surface). Lack of stability in mix, excess binder/fines, soft bitumen, poor aggregate interlock, oscillations set up by vehicles, frequent braking of vehicles, faulty laying of mix. Scarify and relay the surface, cut high spots and fill low spots. Use heater-planer to rectify defects.  
Shallow depressions (localised and limited in size) dipping about 25mm or more below desired profile. Heavier traffic, settlement of lower pavement layers, poor construction method. Fill with premix carpet and compact to desired grade and profile.  
Settlement (large localised deformation which may or may not be generally followed by extensive cracks) Poor compaction of fill, poor drainage in lower layer, inadequate pavement thickness, frost heave or swelling effect of moisture on expansive soil. Excavate defective fill, reconstruct under controlled conditions to required thickness, provide adequate drainage, strengthen the pavement if required.  
d) Disintegration defects
Stripping (loss of adhesion between binder and aggregates in presence of water).

 
Softer grade bitumen, siliceous type of aggregates, rain, soon after laying of surface. Use anti-stripping agent in suitable doses in case of siliceous aggregates, use of proper grade of bitumen for coating, and provide adequate surface drainage  
Loss aggregates (as in surface-dressing)

 
Non uniform spraying of binder, delayed spreading of aggregates, traffic soon after laying, insufficient binder, ageing of binder. Apply liquid seal, fog-seal or slurry-seal. Relay, if necessary with liquid seal with proper quality control.  
Edge breaking (frayed edges) Infiltration of water, softening of foundation, worn-out shoulders with insufficient side support, inadequate thickness at edge. Relay shoulders with good materials and compact provide adequate drainage.  
CARRIAGEWAY MARKING
A broken line shall be used for centre line on two and three lane road, and for traffic lane lines. These lines are for guidance of the drivers and may be crossed at their discretion.
Longitudinal solid lines are used as guiding of regulating lines and are not meant to be crossed by the driver.
a) Road with restricted visibility White centre line to be solid.
b) 4 lane undivided road White centre line to be solid.
c) Edges of road


 
Yellow line to be solid 20-30 cm.h wide 15cm. from edge in respect of 2 lane road. Yellow line to be solid 15 cm. wide 15 cm. from edge for multi lane road with central verge.
Carriageway width transition White centre line solid 10 cm. thick with converging lines solid 10cm. thick for a length of 20 times the offset distance yellow edge line 30 cm. wide.

S
top line indicates where vehicles should stop when directed by a traffic officer or a traffic controlled device on urban and sub urban roads. 2.0 to 3.0 m. from 20 cm. wide located from pedestrian crossing on rural roads. Solid 30.00 cm. wide. 1.25 to 9.0 m. from nearest carriageway of the intersecting road.
