Study Notes
Lane Standards
- Expressways typically have 3.65 meter lanes to accommodate large vehicles and allow for high-speed maneuvering.
- Rural highways have narrower lanes ranging from 3.0 to 3.3 meters due to lower traffic volume.
- Number of lanes on expressways depends on traffic demand with a minimum of two or three lanes in each direction.
- Rural and urban highways utilize asphalt or concrete pavements based on traffic load and local conditions.
Shoulder Standards
- Expressways have wider shoulders measuring 2.5 to 3.0 meters to provide space for emergencies, cyclists, and pedestrians, and act as a buffer zone.
- Rural highways have narrower shoulders ranging from 1.5 to 2.5 meters, primarily for emergency stops and accommodating slow-moving agricultural vehicles.
Sidewalk Standards
- Urban sidewalks have a minimum width of 1.2 meters, with the possibility of expanding to 2.5 meters or more in high-density areas.
- Sidewalks must be accessible for people with disabilities, requiring features like curb ramps, tactile paving, and obstruction-free paths.
- Concrete is the primary material for sidewalks, with some areas using brick or other materials for aesthetics.
Carriageway Standards
- Carriageway width is determined by the type of road and its location.
- Urban areas have wider carriageways ranging from 6.70 to 12 meters to accommodate more lanes for heavier traffic.
- Rural areas have narrower carriageways, typically 7 meters, providing enough space for two vehicles to pass safely.
Concrete Thickness Standards
- Concrete thickness for primary roads and highways in the Philippines is between 280 to 300 millimeters (11 to 12 inches), reinforced with steel dowels in all transverse joints.
- Secondary roads with lower traffic volumes have thinner concrete ranging from 150 to 200 millimeters (6 to 8 inches).
- Proper reinforcement with steel bars or mesh is essential for both primary and secondary roads to prevent cracking and increase pavement lifespan.
