The pelvic outlet. The pelvic outlet (lower pelvic aperture) extends from the pubic symphysis to the tip of the coccyx (its anteroposterior, or conjugate, diameter; see fig. 31-3) and, from side to side, between the ischial tuberosities; hence it is diamond shaped. The outlet is at a slight angle (10 to 15 degrees) to the horizontal.
Average maximum cost of interlocking driveway pavers for 300 square feet: $2,160. Costs for interlocking driveway pavers can fall into several categories. The first category is the price to purchase the pavers and the other necessary materials. The pavers are sold by numerous manufacturers at various quality levels. An average paver costs from $1.23 to $1.50/sf. The substrate for a 1,000-square-foot driveway would cost more than $500, and the concrete would cost around $75. Joint sand would cost under $50. The second category is cost of installation.
Proper Installation. Before installing a paver driveway, the existing concrete or asphalt driveway must be removed and the base must be reworked. Most conventional driveways have about 4 to 6 inches of processed base. All paver driveways should have at least 12 to 14 inches of crushed process for its base layer.
