Research of traffic-flow speed on weaving sections of freeway intersections

[摘要] This article contains: groundwork base's drainage of rigid and flexible permanent road revetments conceptual issues; drainage systems operational schemes; underlayer's working layer hydration types; groundwork drainage measures; drainage systems design calculation criterias; recommended production methods are offered; the most commonly used drainage structures components; criteria for choosing the most suitable material; reasons of road revetments' drainage systems underperformance; comparison of normative and proposed methods for designing drainage systems in the bases of pavement; a forecast of possible changes in normative framework (in order to improve roads' groundwork bases and revetments durability, using modern design calculation methods); drained road revetments durability data; economic feasibility of using drainage systems in the base of pavement.
