As Figure 1 shows, entrance profile (g2) should slope upward (positive grade) from the gutter line to the curb side of the sidewalk (if present). Break-over between the cross slope of the traveled way (g1) and the positive slope of the driveway (g2) should be limited to 9%. Figure 1: Typical curbed entrance profile Figure 4-6 (A) shows the profile of a driveway connecting to the normal cross section of a highway. The cross slope of the highway should be maintained for a minimum distance of 12‟ beyond the edge of pavement Ideally, a graded shoulder width at least 3 to 5 feet wide with a maximum cross slope of 6:1 should be provided on each side of the pathway. At a minimum, a 2 foot graded area with a maximum slope of 6:1 should be provided for clearance from lateral obstructions such as bushes, large rocks, bridge piers, abutments, and poles. See .

Maximum slope 10% or 8% sometimes for footpath. If land is below footpath level, fence line should be 0.1m (minimum) higher than back of path. If land is above footpath level, driveway grate could be provided or allowed for bypass Driveway slope could be up to 25% in maximum For superelevation rates greater than 3 percent and less than 5 percent, a maximum rollover rate of 7 percent will be used to establish the shoulder cross slope. When superelevation rates range from 5 percent to 6 percent, the shoulder cross slope will be 2 percent Specifying a running slope of 7.5% maximum and a cross slope of 1.5% maximum for exterior ramps will accommodate most irregularities or variances due to construction methods or materials according to a study sponsored by the Board (Dimensional Tolerances in Construction and for Surface Accessibility by David Kent Ballast.

The maximum cross-slope is 2 percent. Preferably, walkways should not have steps. Where steps are necessary, cheek walls enclosing the risers and treads should be used to make a smooth transition to planted areas on the sides of the steps if grass is planted Using the profile of the driveway in the first example, determine where to cut your sections, preferably outside the slope line of the main roadway. In this example, the sections will be located at 0+75 and 1+50. These stations were picked at various points along the driveway to get an average cross section area.

Example of a gravel road with good shape of cross section.Notice crown in driving surface and proper shape of shoulder and ditch. Understanding Road Cross Section 3. moisture, material, and subgrade stab-ility vary; therefore, the maximum speed for good maintenance can vary. However, in virtually any condition, it is difficult to exceed 5 mph. For commercial driveways, most cities in the Austin area have a 15% maximum slope for driveways (not to exceed a certain distance)--perhaps that could serve as the basis of your argument. Does the drive cross a sidewalk? Maximum crosslope on a SW is 2%. Most towns around here have an 8% to 10% max slope, but we are naturally flat The low point for rural driveway profiles is generally over the roadside ditch.

The result is a diagonal slope that prevents water from flowing down the length of the driveway, reducing the threat of puddles, ice and damage to the surface. The pitch across the width of the driveway must be 2 to 5 percent.

Maximum grade should not exceed 1:20 in the footpath area or 1:4 within the boundary. Where grades steeper than 12.5% are necessary for driveways of vehicles with low ground clearance, a transition zone at either end of the steep section may be required to prevent vehicles bottoming out on the driveway 2) For project types identified as Limited Scope, if sidewalks cross a curb at a street or driveway, reconstruction of the street or driveway to improve slopes is not required.

A driveway is a vehicle access lane located on private property. A vehicle crossing starts where the driveway leaves the legal boundary of a property and continues until it meets the road. It allows vehicles to cross over berms or pavements to access the road 3 [§ 4.3.7] The cross slope of the curb ramp is perpendicular to the running slope.

In a few cases, the interlocking concrete pave-ment may abut an existing concrete slab. This could be a driveway apron or an abutting street.
